1.What is a Tsunami?
A big wave that causes massive destruction.
2. When did this Tsunami happen? (DATE)
December 26, 2004
3. How many people died, in how many countries?
250,000 people died in 4 countries.
4. What is the name of the warning center in Hawaii?
Pacific Tsunami Warning Center.
5. An area where one tectonic plate is pushing under another is called?
Subduction
6. What magnitude was this earthquake? What is a seismograph?
The seismograph, a machine that measures energy, caught a drawing of the earthquake which was a 9.0,
7. Each unit in magnitude is a factor of 30 of radiant energy of an earthquake.
8. Earthquake scientist get paged when an earthquake of a factor of 6.0 or larger.
9. How do Tsunami sensors buoys work? Explain.
A tsunami buoy is a specialized buoy which is able to detect subtle changes in water pressure which could indicate an incoming tsunami.When a tsunami buoy detects a pressure pattern which could be a tsunami, it immediately sends information to the satellite, and the information is passed on to regional tsunami warning centers.
10,How many warning sensors/buoy's are there in the pacific?
There are 6 sensor buoys.
11.The earthquake was shallow. How many kilometers deep was it?
30 kilometers deep.
12. What is "Tsunami Initiation"? Explain.
When water rises and begins to split in different directions. Or when a sudden offset changes the elevation of the ocean and initiates a water wave that travels outward from the region of sea-floor disruption.
13. How fast does the Tsunami wave travel? Why is this different than a surfers wave?
It can go up to 500 to 1,000 km/h (310 to 620 mph)
14. What does a boat in the open ocean feel during a Tsunami wave?
The boat will barley notice the wave under them.
15. What warning sign often occurs at the beach during a Tsunami? What is Amplification?
When the water goes further into the ocean instead of the beach and severe ground shaking.As a tsunami approaches shorelines, water may recede from the coast, exposing the ocean floor, reefs and fish.Abnormal ocean activity, a wall of water, and an approaching tsunami create a loud "roaring" sound similar to that of a train or jet aircraft.
16. Is there usually only one wave in a Tsunami? Is there a pattern to the waves? Explain.
No. There usually is more waves coming but it could be at any moment, hour, day, week. Yes, the pattern is that some are larger than others.
17. Where is greater damage likely, on a gentle sloping beach or a steeply sloping beach? Explain why.
Gentle slope because the wave can go through it easily.
18. True/False, you are safe as the Tsunami wave is passing back out.
False
19. How did the quake affect the earths day?
It made the weather change and made it darker.
20. What area of the United States is at risk for the same type of earthquake?
The West Coast is more likely at risk since it's the closest to the ocean.
21. What are the four cause of Tsunami? How many people on the earth are at risk of a Tsunami?
Asteroids, earthquakes, volcanoes, and landslides. Millions.
22. What is happening in the Casadia Subduction Zone? What could happen.
Land is going under ground. An Earthquake/Tsunami could happen.
23. What is being done to help prepare for future Tsunami's?
More pressure sensors and monitors being put around most near the countries more at risk.
24. How many more buoys did the United States add to the Pacific Warning System?
39 more buoys.
